In this paper, an extension of two classical viscoelastic models adapted in large deformation for incompressible rubber like materials or soft tissues is proposed. These models are built by using a three dimensional homogeneization by means of a sphere unit approach. Thus several comparisons between classical formulations and homogeneization on a sphere unit formulation is proposed. An adaptation of those models to describe anisotropy is proposed. Finally an extension of those models to take into account stress softening is described.
